Abstract: Realizing the digitization of the meteorological archives with the secure scanning and the OCR (optical character recognition) is an effective way to save and develop the papery historic meteorological archives. Based on the investigation and the experimentation on the digitization technique, a conception about the digitization of the papery historic meteorological archives is presented. Aiming at the character of the content recorded in the meteorological archives, the application of the handwritten numeral recognition of OCR is analyzed, and the resolution strategy of OCR recognition of the meteorological archives is presented, which provides a technical idea and effective technical reference for the construction of the digitization of the papery meteorological archives in the area.The scientific and effective way of the meteorological archive digitization is to utilize the technique of the integrated carrier and the OCR which are advanced at home and abroad, and to found a system platform of the digitization of the meteorological data. The platform is consisted of the high/low secure scanner, personal computer, the storage device, the managing software, the OCR software and the applied software etc. The system integrates the scanning process, the quality control, and the statistical process of the various papery archives and the microfilm archives, creates the electronic files in the unified format and the same medium, realizes the extraction of the data information from the meteorological data in the form of long sequence with OCR technique, and finally solves the problem of protection and the digitization of the library papery meteorological data.The construction of the meteorological archive digitization is not only simple data processing, but also relates to a series of associated techniques including the classification of the meteorological archives, the construction of the standard specification, the secure scanning, OCR technique, the data storage, the construction of the data set and the retrieval and application of the information etc. The construction of the meteorological archive digitization integrates the archives on the different carrier in order to realize the overall application of the protection and digitization of the archives. The resulting electronic documents and the long term digitizing documents have important significance for the protection of the archives and the climatic analysis in the various fields.The primary analysis of the strategy of the digitization of the papery meteorological archives indicates that it is feasible to apply the secure scanning and the OCR technique to the digitization of the papery meteorological archives. At present, the system of the meteorological archive digitization has stepped into the performing phase, and the digitization of the papery historic meteorological archives will provide the foundation for the conservation and the application of the historic meteorological data.
